How to Make a Breakfast Casserole with Sausage and Potatoes

Prep!

There is a little prep work to do for this recipe before you begin.

Preheat your oven to 350°F and grease a 9 x 11 or equivalent sized casserole dish with butter or cooking spray.

Dice the shallot and red pepper and cut the potato into 1/2-inch size cubes.

Shred the cheddar cheese, if necessary.

Tip: it is recommended to shred the cheese from a block for the best melting and texture. Bagged shredded cheese contains a starch that can make your cheese gritty when melted.

Create!

Add 1 tablespoon of olive oil to a large skillet over medium-high heat.

Add the shallot and pepper and a pinch of salt and pepper. Cook until just soft, about 2-3 minutes.

Add the ground sausage and cook, breaking up, until no longer pink, about 5-7 minutes.

Meanwhile, heat a second large skillet over medium high, add 1 tablespoon of olive oil, and the potatoes. Season with just a pinch of salt and pepper.

Cook until the potatoes are just slightly tender, about 10 minutes. They will finish cooking in the oven.

While the sausage and potatoes are cooking, crack your eggs into a medium bowl, season with salt and pepper and whisk in the milk until blended.

After the sausage and potatoes are done cooking, layer everything into the casserole dish by adding half of the eggs, sausage, potatoes, and cheddar cheese and then repeating with the remaining half.

Bake for about 40 minutes, or until just set in the center.

Present!

Topped with some fresh herbs like parsley or sliced green onions.

Serve hot.
